WorldOnGo for iPhone (Support Page)

01-21-2012: We have just uploaded an update for WorldOnGo that should fix the black captcha image problem mentioned below. The app will be available for downlaod as soon as it is approved by App Store. App Store generally takes about a week to approve updates.

01-14-2012: Vonage has updated thier website yet again, and that is what making the capthca image area appear black in our iPhone application. We believe we can solve this issue and are working on a fix. We will release an update as soon as we resolve the issue.

09-01-2011:Vonage has updated thier website and are now requiring captcha image verification when setting an international number as the call forward number. This is causing WorldOnGo not to function correctly. We foresaw this as a possible move by Vonage to prevent our app from setting the call forward and that is why we mentioned in our app description that this app may not work if Voange makes any changes to thier website. We are looking into this problem and hopefully can find a solution. There is no work around for this problem. You can still use this app to reset call forward to a US number or disable call forward.

08-10-2011: A few users have reported that the international calls are not getting forwarded, instead calls are being routed to Vonage home number. This seems to be an issue with how Vonage is forwarding calls. Now, Vonage is taking about five minutes to make call forward settings active. So, please turn on the call prompt in Settings-Advanced Settings and wait about 5 minutes before clicking Call button. Please do not quit the app, as quitting the app will reset the call forward in the background.
If it is still not working, you need to contact Vonage support team and ask why international call forward settings are not becoming active immediately.

Why is not the app launching after installing the latest update?

A bug got introduced with the update 3.1.5 that is prevening the app from launching on iOS 3.x devices. We have found the root cause of the problem and are working on a fix. We will make the fix available as soon as possible. We apologize for the inconvenience. If you have already updated your app to this version, the temporary work arounds are

1) upgrade your iOS to 4.x. We understand if you don't want to.

2) If you have bought previous version of the app and have backed up your iPhone, you can restore the phone to that back up and use the app.

We will have the fix available as soon as possible and again, we apologize for the inconvenience.

Stuck with Call prompt after upgrading to 2.9.5. What is the work around and when will we get the fix?

Update: We have released an update for this fix. Just update to the latest version.
This bug was introduced with version 2.9.5 of WorldOnGo, but the work around is simple. Please go to Settings->Advanced Settings and turn off the 'Show Call Prompt'. We have already submitted an update to the App Store and it should be available for download by end of this week or early next week. We apologize for the inconvenience

After configuring call forward, when I call my Vonage number, it goes to my Vonage voicemail. What is the reason and what is the solution?

It is most likely a problem with your Vonage account or it is just that Vonage lines are busy. As a precaution, please check your Voicemail settings at Make sure calls are forwarded to voicemail after 50 seconds. Also try calling a different country or a different phone number. If it continues to happen, please contact us at and we will futher toubleshoot the problem.

Why isn't WorldOnGo disabling call forward after the call is connected?

Please make sure 'Call Forward' Setting is off in Settings->Advanced Settings section. If the call forward is not being disabled even after that, please contact us Our support team will be more than happy to resolve the problem.

Recently, WorldOnGo is just ringing my home Vonage phone without forwarding the call the to the number I dialed, why?

We have released an update 1.6.5 to address this problem. Also please try the workaround mentioned below if you continue to experience the same problem.

Sometimes, Vonage servers take a few seconds (and that few seconds is random) before they make the call forward settings effective. WorldOnGo already waits a few seconds before calling your Vonage number, but it seems that is not enough these days. We are already looking into this problem and will try to release fix if the problem is wide spread.

Meanwhile to work around this problem, in WorldOnGo app, go to Settings->Advanced Settings. Locate call prompt option and set it to 'On' position and save your settings. Next time when you make call, once the call forward is configured the app will show an alert dialog prompting you to call your Vonage number. At this time, wait a few more secs (5 to 15 sec) before clicking the call button. Please try this work around and let us know your findings.

With the new feature to reset call forward on call connect ( added in 1.6.3 update), it is hard to turn on speaker phone and access other phone controls. Is there a work around?

Yes, when WorldOnGo re-launches to reset call forward, it pushes the phone application to background and makes it hard to access phone controls. We are working on a fix for this too.

Meanwhile to work around this problem, in WorldOnGo app, go to Settings->Advanced Settings. Locate 'Reset on Call Connect' and set it to 'Off' position. But please remember to launch WorldOnGo after you are done accessing the phone contols, to reset call forward settings on your Vonage account.

What prefix do I use to dial an international number?
We recommend you save all your international numbers in +CountryCode XXXXXXXXXX format. We will add the right prefix based on your country. We also support 011 ContryCode XXXXXXXXXX format (for US and Canada) and 00 CountryCode XXXXXXXXXX (for UK).

How do I avoid using air minutes if I am near a land line outside my home?
In the Settings tab, enable Prompt Call. If you enable this flag, the app will prompt you before calling. At that time, you can just quit the app and call your Vonage number from any other phone. After your call is connected, don't forget to RELAUNCH the app to reset call forward settings.

I generally configure my vonage phone to ring my cell phone simultaneously. Can this app restore those settings?
Yes, you can do that by configuring default call forward settings accordingly. To configure default call forward settings, launch WorldOnGo. go to Settings tab and then go to Default Call Forward Settings. Here, enable Call Forward, enable SimulRing and then enter the phone number you want to ring simultaneously. When ever WorldOnGo resets call forwarding, it will reset it to these values.

I know, WorldOnGo resets my call forward after the call ends. But I want call forward to be reset as soon as my call is connected. How can I do that?
Once your call is connected, press 'Home' button on the iPhone. Click on the WorldOnGo app. WorldOnGo will launch and will reset call forward automatically.
